Letters Patent No. 109,322, dated November 15, "1870,

I IMPROVEMENT lN' MOWING- MACHINES.

The Schedule referred to in these Letters Patent and making part of the name.

To all whom it may concern The nature of ,my invention consists in the construction and arrangement of a mowing-machine, as will be hereinafter fullyset forth.

In order to enable others skilled in the'art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in whichv Figure 1 is a plan view of my inowing-machine;

Figure 2 isa side elevation of the same, one wheel being removed;

Figure 3 is a rear view of the frame; and

Figure 4 is a view of the inner side of one of the wheels. I

A represents the frame of my machine, through which passes the axle a; v

Outside of the frame A, on each end of the axle,

is secured a sleeve orv collar, 1), having, at its inner:

end, a toothed wheel, d.

On the collar 1; is placed the wheel B, which, onits inner side, is provided with a pivoted'pawl, c, pressed against. the toothed wheel 01, and so arranged that, when the machine moves forward, the axle a will be turned or revolved with the wheels, but, when moving backward, the pawlfe will slide over the teeth of the wheel 01, and not turn the axle.

Upon the axle (1, inside and on each side of the frame A, is secured a wheel, 0, provided, on its periph cry, with a series of steel pins, i t, placed at equal distances apart, and so arranged that each pin on one wheel will be directly oppositc'the center of the space between two pinson the other wheel. 7

Near the rear end, in the center of theframeA, is a vertical shaft, D, provided with two arms, one,

. E, at or near its upper end, and the other, G, at or i on the side, and is hinged to the sickle bar J.

The finger-bar K is hinged to the frame A, and

can, with the sickle-bar, be turned up when it is held along the side, at the front edge of the machine, by the spring-hook 7t.

The vertical rocking-shaft I) may be raised ,up for a short distance by means of a lever, L, attached to a shaft, M, placed horizontally in boxes on the rear end of the frame A.

From this shaft 'an arm, on, extends toward the rear, into and through a slotted car, at, bent upward from the shaft D.

' By this means the plate H will be raised up, so as to disengage it from the pins ll 2'.

The lever L is held in either position-that is, either to bring the plate H in or out of gear with the pins i l',by means of a notched spring-bar,p, catching on a pin, s, on the side of the lever.

This machine, which I call the eccentric diamond mower, has a great many very important advantages 7 over other machines of its kind.

It dispenses with the usual complicated cog-wheeled gearing, the motion being generated by the square steel-lincd plate H moving in a horizontal position from side to side.

The sickle is entirely free from any vibratory movcment, as in the usual crank-gearing, and is not liable to break, as in other machines, the movement-of the sickle in my machine being entirely horizontal.

The construction of the mower,- in avoiding all vi- 1. The lever L, shaft M, arm in, and slotted ear n,

. all constructed and arranged as described, for throwing the plate H in and out of gear with the pins '6 i,

substantially as herein set forth.

I In testimony that I claim the foregoing, I have hereunto set my hand this 13th day of September, 1870.

BENJAMIN ILLIN GWORTH.
